Tommaso Teofili commented on UIMA-1499:
---------------------------------------
we could use generics to ensure this at compile time i.e.
public CasPool(...., Collection<ProcessingResourceMetaData>
aComponentDescriptionsOrMetaData...) ...
what do you think?
> Potential ClassCastException in CasPool
> ---------------------------------------

> Key: UIMA-1499
> URL: https://issues.apache.org/jira/browse/UIMA-1499
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework
> Affects Versions: 2.3
> Reporter: Jörn Kottmann
> Fix For: 2.3
>
>
> The CasPool has a constructor
> CasPool(int aNumInstances, Collection aComponentDescriptionsOrMetaData,
> Properties aPerformanceTuningSettings, ResourceManager
> aResourceManager)
> where aComponentDescriptionsOrMetaData is a collection which can contain
> according
> to javadoc "AnalysisEngineDescription, CollectionReaderDescription,
> CasConsumerDescription or ProcessingResourceMetaData objects"
> A reference of the Collection is passed to fillPool which passes the
> Collection
> to a CasDefinition constructor which then casts everything to
> ProcessingResourceMetaData,
> which will result in a ClassCastException in the case of
> AnalysisEngineDescription,
> CollectionReaderDescription and CasConsumerDescription objects.
